Here is the reworked code for the program for everything but level 2.
The program breaks when you drag the level portal over the character Sprite.
Clean up level2 the code for level 2. Then we can look at pushing the chest. Things get complicated if you want to push the chest off the ledge. Is that what you are thinking. If so we need to switch from a Sprite (images) to physics.body.
Look up the poly simplify thread for the type of logic we would need to worry about when mixing.
@SkyTheCoder although this is 2D portal. It’s still a little complex for a starter project, especially if using box2D. It’s not that different to the way the game arena wraps in Asteroids, or at the sides of the maze in pacman. It’s generally easier if the character completely disappears on one side of the portal before beginning to appear through the other, because then you don’t have to deal with the problem of the character being in two places at once, both graphically and in the physics engine. This is where it could be tricky to use box2D, as it can get glitchy if you try to set positions of a dynamic body directly (dynamic bodies are meant to be acted on by forces, not teleported). You could temporarily switch the body type to kinematic during the teleport action, and then back to dynamic on the other side. Or you could create a new physics body on the other side, and destroy the one that went into the portal, or possibly some combination of both methods.
@SkytheCoder I have thought of trying something much simpler, but my 2D portal project has gone a very long way. aside from that, I don’t know where to start.
@dave1707 Portal is a 3D first-person game in which you solve puzzles using a portal gun to pass obstacles and get to an elevator that takes you to the next level. Here’s a video of gameplay, skip a few minutes into it to see what the puzzles are like:
@Chell I would highly recommend starting with something much, much simpler.
I now have a new problem, I’m trying to have a player pick up a box when the box is tapped and once the box is tapped again, the box would be dropped. I’m working on gravity after this problem is solved.
I still have the same problem, but no one’s responded to my replies. Hopefully someone could solve my problem of having my box stuck between two portals.

It’s been a very long while since the last person replied to anything on this thread, even if it was a move on to something else response. But I still work on my project alone as I used to do awhile back. But I wish someone could help me now with all of the small and short problems in the now seven levels of my game.
@Chell I don’t know what you want. I’ve already given you several examples of moving a character from portal to portal going to different levels.
Actually, I’ve moved on from the portals and onto the game’s physics. I need to know how to create a button than activates the door’s teleport function.
I’ve been trying really hard to work on the problem on my own. But with nfgdayton missing I’m having a hard time solving the problem I’ve stated. So can you please help me?
Just create a button on the screen. When it’s touched, set a flag to true. When it’s touched again, set the flag to false. If the flag is true, allow what ever function the portal does to execute. If it’s false, then don’t allow what ever function the portal does.
I’m having some trouble. I’m trying to create a function where you place the sprite on a red rectangle (or the weighted cube on the button), the door function should be set to true. But this is only working on my second level where this function is first used. Here is my code.
function level2()
background(50, 61, 130, 255)
level2Paint()
if zx>ex and ey<zy and dx>sx-20 and dx<sx+20 and dy>sy-20 and dy<sy+20 then
sx = vx
sy = vy
lv=lv+1
end
sprite("Documents:Cube",zx,zy,50,50)
--in Portal?
if dx>sx+20 and dx<sx+20 and dy>sy-20 and dy<sy+20 then
sx = vx
sy = vy
--in case xport elipse overlaps portals
moved=true
moved1=true
end
end
-- when character and object are in the portal at the same time moved variables get messed
